The frame is fitted to the outer firebox by locating the flanges inside the outer firebox. The slots in the frame sides 
should align with the threaded holes. Ensure the frame is the correct way up. If they do not align then, either the 
frame has been positioned upside down or the outer box has been twisted out of square to the wall during fitting.

 

The screws can now be fitted as shown in the photo below.

 

Small adjustments of the frame can be made if required due to the slots.

 

Ensure that the frame is not pressed tight against any plastered surface or surface that is likely to mark. 

 

 

Once the frame has been fitted, then finally, the door can now be refitted

 

See Door Removal/Replacement. 

Check the door seals correctly.

 

Check  that the inner firebox  is flush with  the  frame when  the  door is  fitted.  If  it is  not  then  the inner 
firebox  needs  to  be  brought  forward.  See  secti

on  on inner  firebox “engine”  fitting.  Failure to  do this 

could result in the air intake at the back of the inner box becoming blocked off effecting the operation 
of the fire.

 

 

Commissioning 

 

After Installation Is Complete

 

In your own interest and for safety, in the United Kingdom, it is the law that all solid fuel appliances are installed 
by  competent  persons,  a  registered  installer  or  approved  by  your  local  building  control  officer. 

The  Heating 

Equipment Testing and Approval Scheme (HETAS) require its members to work to recognised standards.

 

Door Tension Adjustment

 

The door tension latch is factory set to give the optimum pressure on the door seal. It should not normally need 
any adjustment until after the stove has had some considerable use or has had the glass replaced. However, 
after installation and before commissioning check the door latch tension. If it needs tensioning then see section 
in Servicing Instructions.

 

 

Air Supply

 

When commissioning the fire ensure that the air supply is adequate for the fire. An air supply may be required in 
homes which have high levels of air tightness even if the fire output is 5kW or less. Particular attention should be 
observed if there is a ceiling fan or extractor fan in the room or adjoining room as this may have an effect on the 
draw of the flue / fire. The fire should be tested with the ceiling or extractor fan on and with all inter-connecting 
doors to the room closed and then open. If required additional air may be required to overcome the extractor or 
fan pressure.
